STACKER FOR THRESHING-MACHINES.-

SPECIFICATION forming part of Letters Patent No 681,007, dated August 20, 1901.

7 Application filed January 1901. serial No. 45,24. (No model.)

To aZZ whom it may concern/ Be it known that we, EDGAR P. WATROUS and LEROY VAN BENSOHOTEN, of Groton, in the county of Tompkins, in the State of New York, have invented new and usefullmprovements in Stackers for Threshing-Machines, of

which the following, taken in connection with the accompanying drawings, is a full, clear,

. may readily manipulate the device from the floor upon which the machine rests for directing the discharge of the straw and chaff to any desired locality within the range of the stacker.

To this end the invention consists in the combination, arrangement, and detail construction of the parts of a stacker, as hereinafter fully described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a longitudinal vertical sectional view of our improved stacker and the adjacent portion of a threshing-machine to which it is attached,

. the outer endand hood of the stacker being shown in elevation and the gear-case being omitted to avoid confusion of the more essential parts. Fig. 2 is a detail plan view of one of the supports for the discharge-chute. Fig. 3 is a perspective view of the device seen in Fig 1, portions of the fan casing being broken away and a gear-case and crossbar belng omitted for disclosing the interior and underlying parts of the invention. Fig. 4: is a detail sectionalview of the drivinggears for the fan, showing the inclosing case and bearings for the gears and shafts in section.

Fig. 5 is a perspective view of one of the detached elbow-sections seen in Figs. 1 and 3.

Similarreference characters indicate corresponding parts in all the views.

This invention consists, essentially, of a tilting chute or discharge-conduit A, having its free end provided with separated annular shoulders at a; a hood B, pivoted at b to an annular ring I), which is revolnbly mounted on the outer end of the chute A between the shoulders Ct to, and a fan C, revolubly mounted in an independently-revolving fan case D. The chute or discharge-conduit A is preferably composed of end and intermediate sections 25, 1;, and u, telescoping with each other, the inner end of the inner section t being hinged at c to the adjacent portion of the fan-case, which in turn is revolnbly supported by the adjacent end of the threshing-machine frame E, a portion of which is seen in Figs. 1 and 3. This inner section 25 forms a support for the intermediate and outer sections it and t, the section "a being movable lengthwise of the outer end of the section if and the section 7) being movable by hand lengthwise of and upon the outer end of the section, a for removing the same, if desired, it being detachably interlocked with the section to. The shoulders at a are formed upon the outer end of the section t" and serve to hold the ring I) from endwise movement or displacement. The pivotal pins 17 project laterally from opposite sides of the ring I) and form suitable trunnions for supporting the hood B and permitting its oscillatory movement. The hood B usually consists of a semicylindrical shell, having its inner end mounted on the trunnions b and provided with a reinforcing-band formed with depending ears V and its outer end terminating in a substantially semiconical deflector for di Verting the straw, chaff, &c., from the mouth of the chute in any desired direction, it being understood that said hood is revoluble with the annular ring 1). Suitable springs W are interposed between the ears V and ring I) for forcing and holding the hood B in its normal upwardly-inclined position.

The means for controlling the position of the hood B generally consists of a rope or cord Y, having corresponding ends passed in opposite directions around the pulleys X on the chute A and secured to the ears V of the hood B, the opposite ends of said cords being adapted to be secured to a fastening member 19, also pgovided on the chute A, in proximity to its inner end.

The means for supporting the free end of the chute A preferably consists of a tubular arm N and a hoisting cable or rope d, the arm N being pivotally secured at one end to suitable ears Z on the lower face of the inner end of the discharge-chute A and having its outer free end provided with rollers or spools T, having concave bearing-faces upon which the lower face of the chute A normally rests.

The arm N usually extends outwardly be yond the inner end of the intermediate chutesection it, and the rollers T are normally engaged with the lower face of said intermediate section and serve as a roller-bearing for supporting the section it and permitting the same to be readily and easily moved length-f wise of the section If when desired to extend or shorten the chute.

The means for moving the chute-section u lengthwise of the section 25 preferablyconsists of a sprocket e and a chain 71, connected to' the chute u, the sprocket being mounted on a spindle journaled in the ears Z and-driven by a suitable hand-crank or equivalent de-' vice, Figs. 2 and 3, and the chain 'i being passed over thesprocket and a suitable idler fon the supporting-shaft 'u of the rollers T. i The opposite ends of the arm N are usually' bifurcated to receive the sprocket eand rollers T, respectively, the inner end of said arm being mounted on the sprocket-shaft supported by the ears Z and the outer end being arranged to support the spindle 'U and the A re connected to arms'mounted on the shaft 1) of the arm N, and its other end is passed over suitable sheaves or pulleys, which are connected, respectively, to the bail U and upper This lat part of the threshing-machine E.

. ter end of the cord (1 is secured to and adapted to be wound upon a drum, which is provided with a crank-arm o and a ratchet-wheel and is held in its adjusted position by a pawl normally forced into engagement with the ratchet-wheel by a spring 5.

It is evident from the foregoing description 7 that the chute A may be readily rocked upon its pivotal support or hinge c by the cable d and crank o,and that the hood'B may also be rocked upon the pivots b or rotated upon the end of the section 1L by the cable Y; but it is obvious that other equivalent means may be employed for effecting these results and that other devices than the one described may be used for the support and extension of the chute, if desired.

In order to form a continuous .chute and at the same time permit the same to be tilted to any desired angle, we generally provide a flexible elbow, consisting of a series of overlapping split sections M, pivoted to the hinge c and adapted to telescope with each other, the end sections being arranged to telescope with the adjacent portions of the fan-case and chute-section 25, respectively. These elbowsections M are each provided at their meeting edges with apertured ears for receiving the pivotal pin of the hinge c, said ears being interposed between the hinge-sections and concealed thereby and are also formed attheir opposite edges with oppositely-turned flanges Z for limiting the expansion of the elbow, one of said fiangesof each section being provided with lateral shoulders which, to-

gether with the flanges Z, serve to prevent undue movementof the sections M and to form a substantially dust-proof joint. The outer flange of each section M is arranged to lap upon the inner face of the next adjacent section, it being understood that the portion of the fan-case D adjacent to the chute is formed with a discharge opening alined with the chute and is provided with an annular shoulder projecting into the adjacent section M.

The inner end of the chute-section t is also provided with a flange similar to the flanges Z and is adapted to inclose the adjacent end of the outer section M. In order to relieve the strain upon the elbow-sections M incidental to undue upward movement of the chute, we provide a suitable stop, as a chain 2 or its equivalent, having its opposite ends secured, respectively, to the lower faces of the adjacent ends of the fan-case D and chutesection if.

The chain '8 may be secured to the intermediate chute-section in any desired manner, as by a pin or lug 1, projecting into engagement with one of the links or shoulders of the chain, so that when the chain is moved in either direction the sections to and 11 will be similarly moved and the chute extended or shortened thereby.

The fan is revoluble and is preferably suspended upon a hanger rod or support G, having its opposite ends threaded, the upper end being adjustably secured to the bar K of the frame of the threshing-machine E by a suitable nut engaged with the threaded upper end of said rod and its lower end is prO- videdwith an adjustable bearing h and an adjusting-nut adapted to hold said bearing in position and to permit its removal when desired. This fan-case is further supported by one or more frame-bars J, secured to the frame of the machine and carrying a hollow support or sleeve F, encircling the lower end I I I A i with anannular flange encircling the openof the rod G and having its lower face resting upon the bearing h and its upper face ,aformed with an oil pocket or recess 71. The

i, upper end of the support or sleeve F is provided with a circular toothed rack arranged in proximity to the lower face of the fan-case,

which is provided with a spring actuated latch or sliding bolt adapted to engage the teeth of the rack for holding the fan-case in its adjusted position and permitting the same to be rotated for moving the chute laterally chute A. The lower wall of the fan-case is provided with a plate H, having a supporting-guide for the latch I, and is formed with an annular bearing-face resting on the upper face of the sleeve F and with a hollow depending hub g, projecting into the sleeve F and terminating above the bearing 72,.

i i The upper wall of the case D is provided ing in said Wall and surrounding the depending annular flange at the base of the hopper of the machine, thus forming a substantially dust-proof connection between said hopper and the fan-case and permitting the straw, chaff, 850., to be readily discharged from the machine to the fan-case, these flanges also serving as a bearing for the upper portion of the revolving fan-case and to relieve the strain upon the sleeve F. The upper and lower portions of the sleeve F are provided with annular bearings engaged with the peripheral faces of the hub of the plate H for additionally supporting the fan-case, the intermediate portion of said sleeve F between the latter bearings being usually formed of greater diameter than the hub of the plate II for forming bearings adjacent thereto.

anoil-well j, which, together with the oil-recess h, is adapted to hold a lubricant for the The fan 0 may be of any desired form or size for drawing the straw, chaff, and dust through the hopper of the machine into the fan-case and forcing the same outwardly through the chute A and usually consists of a series of blades mounted on a suitable hub, which is secured to a revolving tubular shaft Z. This tubular shaft or sleeve Z encircles the hanger-rod G, extends through the openings in the lower and upper walls of the fan-case D, and is retated by gears L, one of which is secured to e the upper end of the sleeve or hollow shaft Z driven by suitable cone-pulleys (not illusand the other is secured to a suitable drivingshaft or, Figs. 3 and 4, which is generally trated) for permitting differential speeds for the fan 0. These gears L and the adjacent ends of the shaft a and Z are preferably inclosed in a dust-proof case to, depending from the bar K and secured thereto, the walls of said case being provided with antifrictionbearings for supporting the adjacent ends of the shafts a Z.

The lower end face of the hollow shaft Z and the adjacent upper face of the bearings h are each provided with an annular groove for receiving antifriction-balls g, which support the revolving shaft Z and the mechanism mounted thereon, and the sleeve F and cap h are provided, respectively, with an oil-supply cup and a drainage-cock leading to and from the bearing 9. As previously stated, the hollow shaft Z extends through the hub of the plate H, is formed of less diameter than the interior of said hub for forming suitable oil-pockets, and is encircled by an annular packing-ring 5, formed of felt or similar material, for preventing the accumulation of dust in the bearings g, the upper end of said sleeve Z being also closed by the dustproof casing or cap w.

In the operation of ourinvention the latch I is withdrawn from engagement with the rack of the sleeve F, the fan-casing is rotated for moving the chute A laterally to the desired position, the latch I is then permitted to engage the teeth of said rack for locking the fan-case from further movement, the chute A is extended or shortened by the sprocket e and chain 71 and tilted to the desired position by the cabled and crank o, and the hood B is then rotated or tilted by the cord or cable Y for additionally directing the discharge of the straw, chaif, &c., from the machine. It is obvious, however, that when desired tospread the straw, 650., over a considerable area the latch I may be permanently withdrawn from the rack and the fan-case rotated or rocked by hand or by any mechan ical means. (Not necessary to herein illustrate or describe.)

The operation of our invention will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be noted that some change may be made in the detail construction and arrangement of the parts of our invention without departing from the spirit thereof.
